EVENT DESCRIPTION
You will first choose the diamond that will accompany you throughout the course. You will then precisely observe it to determine its characteristics, according to the 4Cs grading system. You will also learn how to measure the diamond’s proportions. At the end of the course, you will have completed an entire grading report and will have discovered the different steps necessary to analyze the quality of a diamond.
